She's only 6, only been doing class for 9 months, and is ready for level 3? That would be a phenomenal gymnast! Does she have back handsprings, straight leg leaps (floor and beam), handstands to vertical (floor and beam), shoot through and mill circle? If the answer to most of these is no, then she's not ready for 3. She could do silver, though. If she has all this in such a short time, then Wow!, stay at the top gym. But seriously, if she doesn't have or is not close to having those level 3 skills, she will not be successful at her meets. There's a lot to consider here. Don't rush into any decisions, it's a long journey, do what's best for your child.
